There are some fundamental flaws in this blog:
1. As the frames are removed from my polystyrene nuc boxes and become empty, they are first put on the cleaning table and as much of the physical wax and propolis debris is removed carefully with a narrow wallpaper scraper.
No need to remove propolis .. just scrape any excess comb off.
Good point, agree. Propolis is anti-bacterial and beneficial eg on brood box walls. It does need scraping off though when it builds up, making it hard to slide frames / conduct hive inspections smoothly & quickly.
2. After cleaning the next step is to sterilise it in the tub of bleach solution. I bought this
60L tub from Amazon. It has blanked off handle holes. There is also a lid available, but I use a shallower tub as a lid. This is also handy for storing tools and other bits and pieces.
Why is this necessary ? I deplore this desire to remove all vestiges of pathogens ... there AREN'T USUALLY ANY THERE. Unless the colony has had one to the Foulbroods totally unneccessary.
Not easy to sterilise polynucs in anything other than bleach. Good for killing chalk brood spores and any other fungal spores which can turn boxes black in storage
3. To prevent pathogen build-up, brood comb in colonies is replaced regularly. By using brood comb replacement, bailey comb change or shook swarm, at least every two years. OMG - When are they going to learn ... Brood frames and comb do NOT need to be changed automatically every two years ... what a waste of bee effort and a totally unnecessary process. Change combs when they are past their useful life not when an arbitrary time frame of "less than" 2 years dictates.
Good practise to change combs every 2-3 years to keep free of pathogens, retain bee cell size (rather than buildup with cocoons). Agree that common sense should prevail e.g a food comb that hasn't had much brood in will last longer than combs in the centre of the nest
There are more in this blog - I lost the will to live reading this much passed on TRIPE !!
The point is, get into good habits early and look after your equipment and bees (the advice given is based on the NBU unit leaflet on sterilising & cleaning equipment). Read around and choose methods to save time & that fit with your values / ways of managing your bees.
